vb.net位或 vbnet ui

请问在VB.net中如何实现跳转到指定位置的?Sub Main()
Dim Ispath As String
Console.Write("请输入目录vb.net位或:")
Ispath = Console.ReadLine()
Do While (Not Directory.Exists(Trim(Ispath)))
Console.WriteLine("你输入vb.net位或的目录不存在,请检查重新输入.")
Console.Write("请输入目录:")
Ispath = Console.ReadLine()
Loop
Console.WriteLine("目录为:{0}", Ispath)
Console.ReadLine()
End Sub
如何用vb.net向串口发送十六位进制数据下面代码就是将文本框中以一个空格隔开的十六进制转为字节的代码,文本框中数字格式为:01 02 03
Dim TestArray() As String = Split(TextBox1.Text)
Dim hexBytes() As Byte
ReDim hexBytes(TestArray.Length - 1)
Dim i As Integer
For i = 0 To TestArray.Length - 1
hexBytes(i) = Val("h"TestArray(i))
Next
SerialPort.Write(hexBytes, 0, hexBytes.Length)
如何在VB(不是VB.net)中使用正则表达式控制文本框只能输入2位小数?(不能输入0000. 或者... 之类的)'最多两位小数,可以没有或者一位
Private Sub TestReg(strData As String)
Dim zq As Boolean
Dim reg As Object
Dim matchs As Object, match As Object
Set reg = CreateObject("vbscript.regExp")
reg.Global = True
reg.IgnoreCase = True
reg.MultiLine = True
reg.Pattern = "^(?!0 (?:\.0 )?$)(?:[1-9]\d*|0)(?:\.\d{1,2})?$"
Set matchs = reg.Execute(strData)
For Each match In matchs
strData = https://www.04ip.com/post/match
zq = True
Next
If zq = False Then strDatahttps://www.04ip.com/post/= "" '清空文本框数据,你也可以改为其他提示
End Sub
Private Sub Command1_Click()
Dim strData As String
strData = https://www.04ip.com/post/Text1.Text
TestReg strData
Text1.Text = strData
End Sub
